17 Claims.

This invention relates to a device for continuously applying acontrolled quantity of liquid, such as oil or other dressing, to atextile thread while the thread is being wound onto a cone, cop, or

the like.

The invention is particularly applicable to winding machines in which athread is wound onto a cone or cop at variable linear speeds.

An object of the invention is to provide for the uniform treatment ofthe thread throughout the winding operation.

Another object of'the invention is to provide a device of the above typewhich may be applied to a standard winding machine.

Another object is to provide a device which is adapted to control therate of liquid supply in accordance with the linear speed of the threadso as to maintain a uniform distribution of the liquid over the entirelength of the thread.

. Another object is to provide a device which is economical in use ofthe liquid and which is simple and cheap to construct and install.

Still another object is to provide a device of the above type which maybe readily adjusted or varied to meet the requirements of a particularcase. r

The invention also consists in certain new and useful features ofconstruction and combinations of parts hereinafter set forth andclaimed.

I Although the novel features which are believed to be characteristic ofthis invention will be pointed out more particularly in the claimsappended hereto, the invention, as for its objects and advantages andthe manner in which it may be carried out, may be better understood byreferring to the following description, taken in connection with theaccompanying drawings forming a part thereof, in which:

In the following description and in the claims various details will beidentified by specific names for convenience, but they are intended tobas generic in their application as the art will permit.

Referring to the drawings more in detail, the

. or cops 14 suitable for fabrication.

Inasmuch a. the winding machine may include duplicate mechanisms tosimultaneously wind and treat a plurality of threads, the descriptionwill be confined to a mechanism adapted to cooperate with a singlethread. Two such mechanisms have been illustrated to show the relativepositions of the parts near the beginning and end, respectively, of awinding operation. It is to be understood, however, that the machinewill incorporate as many such mechanisms as may be desired.

Referring more particularly to one of the winding mechanisms, the threadfrom the source 11 is first passed through stationary thread guides 15and 16, thence over the wiper roll 12 and through a movable thread guide1'7, by which the relative position of the thread and the surface of thewiper roll is controlled. The thread is then passed through a stationarythread guide 18, a tensioning device 19 and through a traversing threadguide 20 by which it is directed onto the core or cone 14 which is beingwound on the rotating spindle 13.

The spindle 13 is rotatably mounted on the frame of the machine and isadapted to be .operated by any suitable driving means, not

shown. The traversing thread guide 20 is adapting the winding operationfor causing the thread to be wound thereon in helical courses ofprogressively increasing diameters. The traversing thread guide 20 ismounted on a support 26 which is pivoted to the frame 25 in any suitablemanner. The support 26 is provided with a counterweight 27 adapted topermit the support to swing about its pivot and to maintain the guide 20in contact with the mass of thread on the spindle 13.

The tensioning device 19 may comprise a pair .100 of comb members (notshown) which are mounted on the frame 25, as by means of a bracket 32,and are adapted to control the tension of the thread as it passes to thecone 14. Suitable well-known means may be provided to adjust thistensioning device 19 in accordance with the linear speed of the threadas the diameter of the cone 14 increases.

The movable thread guide 17 is carried by 'a slide 35 which is adaptedto slide on a rod 36 mounted to 1 extend longitudinally of the roll 12.The rod 36 may extend parallel to the axis of the roll 12 or may beinclined thereto as may be desired. The rod 36 may, for example, besupported at one end by a cam bar 38 which is secured in any suitablemanner in a boss 39 on a bracket 40. This bracket 40 may be carried byan arm 41 which may be secured to the bracket 32. The arm 41 is alsoadapted to support the stationary thread guide 18 which may beadjustable if desired. The rod 36 may be supported independently of thebar 38 if desired, as, for example, directly from the bracket 40;

The slide 35 may be operated by a link 45 which is pivotally connectedto an arm 46 carried by the support 26. The arm 46 may be pivoted tosaid support 26 as at 47 and may be held in adjusted position by meansof a set screw 48 passing through an elongated slot 49 in such arm.

Obviously, the means for supporting the movable guide 17 may be varied,provided the relationship between the movable thread guide 17 and thecam bar 38 is such that the thread engages the bar in passing over theroll from the thread guide 16. The length of the arc of contact of thethread with the roll is determined by the longitudinal position of thethread on the cam bar at any particular instant. The angle of the arc ofcontact of the thread with respect to the transverse plane of the rollis determined by the longitudinal position of the thread guide 17 whichis in turn go erned by the pivotal position of the support 26.

The wiper roll 12 may be mounted on a shaft 50 which may be held insuitable bearings in a support 51 .carried by a trough 52. The trough 52may be carried by the frame of the machine in any suitable way and isadapted to contain a quantity of liquid into which the roll 12 clips asit is rotated. The rolls 12 may be operated by suitable belts, notshown, engaging pulleys 55 mounted on theshaft 50,. The stationarythread guides 15 and 16 may be mounted on a plate 56 which may becarried inany suitable manner by -the trough 52. The guide 16 may, forexample,

be threaded into said trough and may carry the plate 56 by means of abushing 57 and a lock nut 58.

Referring to Fig. 1, at the beginning of the winding operation the guide17 takes a position toward the right of the r'od 36, and as the windingprogresses and the-diameter of the cone 14 on the spindle 13 increases,the support 26'is swung in a clockwise direction and causes the guide 17to 'slide to the left. The relationship between the guide 1'? and theguide 16 is such that the angle of the threadto the transverse plane ofthe roll increases as the diameter of the cone 14 increases. This isillustrated by the winding mechanisms at the right and left,respectively, of Figures 1 and 2.

The shape of the cam bar-38 is such that the length of the arc ofcontact'of the thread with the roll 12 also increases as the thread isshifted arc to the transverse plane of the roll increase as a functionof the speed of the thread. This function may be varied by changing theshape of the cam bar 38 and the relative position of the slide 35 withrespect to the support 26, and is preferably such as to maintain auniform distribution of liquid along the thread throughout the windingoperation.

In order to change the adjustment of the device, it is only necessary toraise or lower the cam bar assembly or to remove the cam bar 38 from theboss 39 and to substitute a different bar, or to shape the bar as may berequired to produce the desired results. The position of the slide 35 onthe rod 36 may be varied by a suitable adiustment of the link 45 and ofthe arm 46.

In the above described device, the uniform and continuous application ofliquid causes the-friction of the thread with the various guides andwith the tensioning device to remain uniform and thereby eliminatesfluctuations in tension of the thread which would otherwise be produced.The device provides for a wide variation in the rate of application ofthe liquid to the thread and is adapted to be regulated to compensatefor comparatively great changes in thread speeds and to be adjusted forvarious types and sizes of thread.

The uniform control effected by this device permits the rolls 12 to beoperated at a low speed and reduces the loss of liquid from the roll andfrom the thread. Suitable dampening means may be included in connectionwith the guide 16, if desired, to reduce the vibration of the thread.The reduction in loss of liquid represents a substantial saving in aplant using a large number of winding mechanisms.

While certain preferred embodiments of the invention have been disclosedherein, it is obvious that various changes and modifications may be madetherein, and that the scope of the invention is only to be limited inaccordance with the following claims when interpreted in view of theprior art.
